I just noticed that footnotes on the first and last page of a document get placed differently as demonstrated in this MWE. In this particular example, the problem shows up in a two-column document where the second column is seen by LaTeX to act in the role
of the last page.

\documentclass{article}
\usepackage[landscape,
twocolumn,
margin=0.5in,
]{geometry}
\setlength{\columnsep}{3em}
\setlength{\columnseprule}{0.4pt}
\usepackage{lipsum}
\pagestyle{empty}
\begin{document}
This is a short section\footnote{Hello}
\pagebreak
\setcounter{footnote}{0}
This is a short section\footnote{Hello}
\end{document}

For the purposes of my document, the left and right columns should be identically typeset. So, I'm not happy that the footnotes get placed differently. What I would prefer is that both footnotes get placed as the first footnote in the left hand column.

The \pagebreak command tells LaTeX to break the current page at the point of the command. With the optional argument, a number, you can convert the \pagebreak command from a demand to a request. (For details refer to this answer by egreg). If you don't specify the options, then number 4 is assumed and a page break is inserted immediately.

Coming to your mwe, the \pagebreak is called with only one line of text without any optional arguments. Hence, you have insisted (demanded) for a page break immediately whereas the second page/column gets shipped out naturally. If you want second column to be identical to first column, put a \pagebreak after the second column also.
